NO. People need to stop parroting this line when they clearly don't understand what it actually means.
'Innocent until proven guilty' is a legal term which has a very specific meaning related to proceedings in a court. It means that a defendant in court does not have to walk in and actively prove their innocence - it's up to the prosecution to prove their guilt beyond all reasonable doubt. Unless the prosecuton can do so in line with the thresholds of evidence required, the default is that the defendant leaves the court free. Even then, the presumption of innocence isn't totally absolute. It does not mean that we should all walk around assuming that this guy is innocent and treating him as such. People are always able to use what is presented to them to reasonably form an opinion of the situation and react as such. It doesn't mean we have to wait for a criminal trial before criticising them or make other decisions. For example, employment law does not require the very high standards of proof that a criminal court does.
He's a scumbag and I am happy and comfortable to say so quite openly without waiting for a court case which he could plausibly escape with a technicality.
